The early process of Rigid-flex PCB board is use connector or hotbar process to connect two PCBs with flex board.This combination with the flex board and rigid PCB process is time-consuming and laborious, so customers transfer the assembly to PCB manufacturer to make rigid-flex PCB.
In addition to the price, the use of Rigid-flex Board has many advantages, listed as follows:
It can effectively save the space on the circuit board and save the use of the connector or the HotBar process
Because of flex PCB and rigid PCB get together, so that require the use of connectors or HotBar process space can be saved, saved space is
Ceramic circuit board and Metal PCB are good in heat dissipation of PCB board.The application of the traditional LED heat dissipation substrate,Metal Core PCB (MCPCB) is different from the application range of ceramic heat dissipation substrate.MCPCB is mainly used in the system circuit board.The ceramic circuit board is applied to the LED chip
All PCB board looks almost same from the surface.Through the surface we see differences, and these differences are crucial to the durability and function of the PCB board throughout life.
It is essential that the PCB board have reliable performance both in the manufacturing process and in the actual use.In addition to the relevant
What is backdrilling?
In the high speed signal transmission printed circuit board, part copper of vias becomes the signal transmission"tail" (Stubs),adverse effects on signal transmission,in order achieve better signal integrity, it is necessary to reduce the length of the Stubs in vias,shorter length of the residual Stubs is better for integrity of the signal.
Backdrilling
The warpage of the circuit board will cause the inaccurate positioning of the components.When the PCB is bent at SMT and THT process, the foot of the components are not in line, which will bring many difficulties to the assembly and installation work.
The maximum warpage or distortion of the IPC-6012,
The difference between ENIG and Gold plating on PCB circuit board?
The ENIG and the Gold plating are commonly used in PCB circuit boards. The Gold plating has been widely applied in electronic products due to the advantages of high hardness, wear resistance and no oxidation.ENIG is generated by chemical redox reaction and create a layer of gold
The production process of a flexible printed circuit board is basically similar rigid PCB.For some operations, the flexibility of the laminates requires different devices and completely different processing methods.Most flexible PCB uses a negative method.However, there are some difficulties in the machining of flexible laminated plates and in the process of coaxial
With the rapid development of electronic communication technology, in order to realize high speed and high fidelity transmission of signal, more and more high-frequency circuit boards are used in communication equipment.The dielectric materials used in the high frequency board have excellent electrical properties and good chemical stability, which are mainly
To understand the back drilling offset,It is necessary to understand how to PCB board process.then know the details of any affects of product performance from design to production process.For "back drilling offset", let us talk about what is "back drill", "back drill" is a process for vias,the aim is shorten the via stub
High precision electronic products usually go through three stages: R &D, trial production, mass production, then how to choose the PCB factory at different phase?
Many PCB circuit designers and purchases can't find the right suppliers.
PCB prototype
Low price with bad quality,high quality with high price
Mass production
Big factory don’t need
